Specification of Letters I Patent.

Patented April 20, 1909.

Application filed May 6, 1907. Serial Nol 372,109.

T 0 all whom it may concern:

Be it known that I, PAUL MAUsER, royal commercial councilor, a subject of the King of Wiirtemberg, Germany, and a resident of The present invention relates to recoilloading rifles with sliding barrels, and more especially to the arrangement of the breech and to the locking mechanism for locking the breech bolt. 7

In a previous construction'of mine, for the locking means, a block similar to a rocking cradle is provided, the upper part of which rests with its face against the rear surface of the breech bolt, andits side arms being prolevers or arms in the locking vided with noses or projections which coact with corresponding grooves in the walls of the frame, in order to assure the, compulsory movement of the block in the unlocking and locking direction.

I In accordance with the resent invention twoseparate movable locking and unlocking .levers or arms are provided instead of this block, which levers are located on either side of the breech framejand being mounted in the barrel extension, are free to swing, whereby the compulsory adjustment of the and unlocking positions is effected by the co-action of projections ,on the arms with corresponding ooves inthe frame or in any other part rigidly connected with the frame, The advantage of the present arrangement is that these horizontally or laterally swinging levers or armssupport the breech-bolt on either side symmetrically to the lon itudinal axis of the breech and barrel, an further that by mounting the arms or levers laterally the whole breech system with casing can be kept lower.

. In the accompanying drawings two arrangements of locking lovers are shown constructed in accordance with the present invention, Figure '1 bein'g an elevation partly in'section, Fig. 2 a lan also partly in section, and Fi 3 a an showing a diiferent osition of t e locking levers or arms, while ig. 4 is a plan partly in section showing a modification. I wish it to be distinctl understood, however, that the exampless own by no means limit the number of ossible arrangements, but that a number 0 variationspulsory swing in detail are possible which would still be within the scope of the'invention.

In the construction shown in Fi s. 1,2 and 3, both locking levers or arms I? are onearmed levers or arms, and are pivoted on the pins a in the rear Wall of thebreechbarrel extension h. The pins a are integral with the arms and project far enough into the corresponding sockets in the sides of the barrel extension, to be prevented from falling out.

The compulsory guidance of the levers or arms in t e locking and unlocking positions, is eflected by projections c on the fore ends of the levers or arms, said projections engaging in correspondingly curved recesses g in the upper w'allof the frame g.

The action of' the above described locking mechanism readily understood. In the locking position (Figs. 1 and 2), the locking levers or arms lie with their fore ends inclined inward in such a manner that the fore ends of the levers or arms (which are rounded off to the radius having the centers of. the pins 0, astheir centers) act like singlearmflaps and abut against both sides of the rear surface of thebreech-bolt 7c and thus support the breech-bolt in 'a' symmetrical manner. Upon the barrel and barrel extension oing back, the pins or gprojections c of the evers or arms in the grooves 9 also slide back, the grooves beingso shaped that, when the 5barrel extension has reached its extreme ackward position, the locking levers or arms will have swung out into the unlocking position, is released and is able to ass backward betlg ween the parallel locking evers, as shown in 3.

the construction shown in Fig. 4, the locking levers or arms 6 are not pivoted, as in the first instance, at the rear end of the barrel extension h, but near the center so that they act as double armed levers. The comof the levers or arms I) 6?, for the purpose of locking and unlocking, is effected by projections c the levers or arms I), the corresponding grooves 9 being provided for said projections so that the breech-bolt on the rear ends'of could vary considerabl or arms), and that the relative'supporting mechanism should be automatically moved substantially the whole length-of the in and out, whereby the same should, when moved out, allow a free passage for the breech-bolt to pass backward. A

What I claim as my invention, and desire to secure by patent is:

1. In recoil loading fire arms, the combination with a frame, a movable barrel sliding on the frame and havin an extension, and a breech bolt sliding in t e extension, of bolt locking levers pivoted in the rearward part of the barrel extension and extending) over arrel extension and means for moving the said levers into the locking and unlocking positions.

2. In recoil loading fire arms, the combination with a frame, a movable barrel sliding on the frame and havin an extension, and .a breech bolt sliding in t e extension, of bolt 1 locking levers pivoted in the rearward part of the barrel extension and extendin substantially over the whole length of the liarrel extension, said levers being provided with projections near their fore ends andthe rame having cam slots or rooves, wherein said projections engage, the evers thus being moved like single-arm fla s and in their looking position abutting wit their fore ends on both sides against the rear face of the bolt.

3. In recoil loading fire arms, the combination with a frame, a movable barrel sliding on the frame and havin an extension, and a breech bolt sliding in t 1e extension, of bolt locking levers pivoted in'tlre rearward part of the barrel extension and rovided with projections en aging in cam s ots or grooves of the frame, t e barrel extension having the.

holes for the pins of the locking levers in its rear transverse wall, and lengthwise in its side walls, cavities wherein the levers enter when swung. laterally into the unlocked po-i sition.

In testimony whereof have hereunto set 'my hand in presence of two subscribing witnesses.
